Green courtyards breathe for a big city. Join us to discover oases that improve air quality, promote biodiversity and create a welcoming environment for residents. We will head to Prague 3, where we will visit two normally inaccessible courtyards. Barbora Týcová from the Bieno association, Karel Světlík, coordinator of participatory planning in Prague 3, and the local drivers behind the transformation of these spaces will be our guides. Thanks to their interventions, the courtyards are coming alive with greenery and activities, which helps to build neighborhood relations and improve the quality of living.
